Gentrol Insect Growth Regulator (IGR) 10(1 oz bottles)
Gentrol IGR Concentrate travels deep into wall cavities, cracks and crevices, reaching the stored product pests that other treatments miss. Hydroprene, the active ingredient, prevents stored product pest larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults and future infestations. 1oz. bottle.
